Recently I upgraded gcc to gcc-4.1.1 from gcc-4.0.3 and cleared out the ccache cache believing that cached compiler data across different compiler versions would be useless. However after doing an 'emerge -e world', there's nothing in the cache. I'm inclined to blame a specific unsupported CFLAG, but the ccache statistics don't indicate anything like that. What would cause ccache to not cache any compiler data?
